Modelling of Solar Granulation

The book "Modelling of Solar Granulation" by Christof Obertscheider provides a comprehensive analysis of the mathematical and numerical methods for simulating solar granulation. It addresses the implementation and comparison of various numerical techniques for solving the equations of radiative hydrodynamics. The author presents a two-dimensional model that is simulated using different high-resolution numerical methods, including non-oscillatory and convex non-oscillatory approaches, as well as non-gray, short-characteristic radiative transfer. Additionally, the influence of artificial diffusivities is examined. The second part of the book introduces two astrophysical applications: a high-resolution simulation of a downward-directed plume on the Sun and a gray, three-dimensional simulation of the quiescent Sun. This detailed study is aimed at professionals and students in astrophysics and offers valuable insights into the complex processes of solar granulation.
